where is located the fuel pump amd how to change it?

Change the distributor cap and rotor and the spark plugs first ( Platinum plugs ) The fuel pump is working is the vehicle is running and stalling.

Mine is in the fuel tank what a problem to replace I did it twice. I have 285,000 miles on my truck. 4 or 5 hundred to fix.
